Hi Sam,

That's seriously cool - I looked in to doing something very similar myself,
but ended up not having the time for it.

My experience is that unity3D does not work well on llvmpipe, to the point
where the number of autopilot failures is very high. I wonder if there's
some way around this?

Cheers,
